Logs27: Mutual Information

Steps

1. Training data set
   • p_i: Let's have curry for lunch.
   • q_i: Maybe Coco ichi?
   • p_i+1: Sounds good.
2. Train seq2se
   • X: concat(p_i, q_i)
   • Y: p_i+1

OLD

Steps

• done Make it possible that beam coexists with infer
• Return infer_logis when beam search
• Get logits for predicted_id
• Have beam_logits.
• Refactoring
  • extract attention method.
  • Unify the model class?
• Confirm beam_logits is same size as logits and same values.
• for one beam search result get indices
• Fetch logprob from the indices
• reward back? or make it for multiple.

- Wait ... we'll have to use conversations.db finally? because we need p_seq2seq(a| pi, qi) - Fully understand MI - Read the original paper - Read the original original paper - we did not train a joint model (log p(T|S)−λ log p(T)), but instead trained maximum likelihood models, and used the MMI criterion only during testing. - P_MI is trained by caliculating MI between source and target. - P_RL is trained by RL agents (so that they can get dialogue history)? - Let's check the existing implmentation. - Understand where pi, qi comes from in the training - pi let's eat curry - qi How about kokoichi - pi+1 sounds good - Start always with small model. - Have backward seq2seq training in place. - Find old implementation of mutual information.

MI steps

• Build MI model, this is happening when decoding best N results and mutual information.
